ATPs are the power cell of a cell. Just like a cell, they need to be charged before they can deliver power.
<h3><u>Explanation:</u></h3>
ATP or the Adenosine Triphosphate is a complex molecule containing a Adenine nitrogen base, a ribose sugar and three phosphates being attached with each other in a chain. Adenosine Triphosphate is the power currency of a cell. It just acts like a rechargeable battery. The metabolic and physiological processes of a cell that needs energy, involves the hydrolysis of ATP into ADP and Pi which are Adenosine Diphosphate and Inorganic phosphate respectively.
Now the ATP is discharged and needs to be charged. So the ADPs are charged into ATPs by different processes of respiration like Glycolysis, Kreb's Cycle, Electron Transport Chain etc.
Both the hydrolysis and the condensation of ATP makes the ATP cycle.
Answer:
Option-C
Explanation:
The phospholipids are the major constituents of the cell membrane of a cell. The phospholipids contains the glycerol attached to the phosphate group and forms the hydrophilic heads whereas the fatty acid tails from the hydrophobic portion of the membrane.
The hydrophobic head face outwards whereas the tails face inwards. The structure of the membrane as arranged in bi lipid layer form and in such a way that the membrane molecules can move. The other molecules present in the membrane like the proteins can drift in the membrane.
Thus, Option-C is correct.
DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turned into proteins.
C. plants don't need oxygen, they need carbon dioxide and PRODUCE oxygen. Animals DO. Need oxygen, I mean.
